This study reports a case of pterygium-like proliferation containing postoperative limbal dermoid remnants and its clinicopathological features.
A 79-year-old Japanese woman, with a history of congenital limbal dermoid resection at age 12, presented with a pterygium-like tissue growth in the left eye. Its temporal location and marked thickness with abundant fatty droplets were atypical of primary pterygium. We performed pterygium surgery and ocular surface reconstruction. Pathological findings included squamous metaplasia, neovessels, and elastic degeneration, as well as prominent subepithelial and stromal accumulation of collagen fibers, adipose tissue formation, and presence of a peripheral nerve corresponded with the frequent findings of limbal dermoid. Ki67, a marker for cell proliferation, was immunopositive in pterygial epithelial cells and neovascular endothelial cells, but not in dermoid components.
Although the pathological finding of degenerative elastic fibers indicated the common feature of ultraviolet-induced pterygium, clinical appearances were atypical possibly due to modification with dermoid remnants.

The study was to assess whether paternal factors are associated with low birth weight (LBW), preterm birth (PTB), and small for gestational age (SGA).
A birth cohort study was conducted in 2010-2012 at the Gansu Provincial Maternity and Child Care Hospital, the largest maternity and childcare hospital in Lanzhou, China. Paternal age, ethnicity, educational level, height, weight, smoking, and drinking were collected. Birth outcomes and pregnancy complications were extracted from the medical records.
During the study period, 10,121 participants were included; the overall prevalence of LBW, PTB, and SGA was 7.2, 9.9, and 7.8%, respectively. Paternal higher height (OR?=?0.64 95%CI 0.49, 0.83), higher weight (P for trend &lt;?0.001), and higher BMI (P for trend &lt;?0.001) could decrease the rate of LBW. Paternal higher education (OR?=?0.55, 95%CI 0.43, 0.71) and higher weight (P for trend &lt;?0.001,) were associated with lower rate of PTB. Fathers who smoked more than 6 pack-years were associated with PTB (OR?=?1.31, 95%CI 1.07, 1.61). Paternal BMI &gt;?23.9?kg/m(P for trend &lt;?0.001,) and paternal education which above college (OR?=?0.61, 95%CI 0.50, 0.82) were associated with a lower rate of SGA.
Paternal low education is independently associated with PTB and SGA. Paternal heavy smoking is associated with PTB. Low paternal weight/BMI is independently associated with LBW, PTB, and SGA.
Paternal low education is independently associated with PTB and SGA. Paternal heavy smoking is associated with PTB. Low paternal weight/BMI is independently associated with LBW, PTB, and SGA.Low birth weight rates are increasing in both developed and developing countries. Although several maternal factors have been identified as associated with low birth weight, little is known of economic or organization factors influencing this increase. This study aims to ascertain the twenty-first century relationships between the contextual country factors and low birth weight rates.
We analyse trends of low birth weight rates in Organisation for Economic Co-operation and Development (OECD) countries. Data from 2000 to 2015 were obtained from the OECD data base. Their relationships with demographic and economic variables, health habits, woman-related preventive measures, health care system organization and funding, health care work force and obstetric care were analysed using random-effects linear regression.
Low birth weight rates are higher in Southern Europe (7.61%) and lower in Northern Europe (4.68%). Low birth weight rates escalated about 20% in Southern Europe and to less extent in Easter Europeg health care coverage or investment in public health system, are directly associated with lower LBW rates.Cone-beam computed tomography (CBCT) has become an increasingly important medical imaging modality in orthopedic operating rooms. Metal implants and related image artifacts create challenges for image quality optimization in CBCT. The purpose of this study was to develop a robust and quantitative method for the comprehensive determination of metal artifacts in novel CBCT applications.
The image quality of an O-arm CBCT device was assessed with an anthropomorphic pelvis phantom in the presence of metal implants. Three different kilovoltage and two different exposure settings were used to scan the phantom both with and without the presence of metal rods.
The amount of metal artifact was related to the applied CBCT imaging protocol parameters. The size of the artifact was moderate with all imaging settings. The highest applied kilovoltage and exposure level distinctly increased artifact severity.
The developed method offers a practical and robust way to quantify metal artifacts in CBCT. https://www.selleckchem.com/products/Obatoclax-Mesylate.html Changes in imaging parameters may have nonlinear effects on image quality which are not anticipated based on physics.

However, researches on 30-day unexpected rehospitalzation of incident peritoneal dialysis (PD) patients were limited. This study aimed to investigate the prevalence, risk factors and impact on outcomes of 30-day unexpected rehospitalization in incident PD patients.
This was a retrospective cohort study. Patients who accepted PD catheter implantation in our centre from Jan 1, 2006 to Dec 31, 2013 and regular follow-up were included. The demographic characteristics, laboratory parameters, and rehospitalization data were collected and analyzed. The primary outcome was all-cause mortality, and the secondary outcomes included cardiovascular disease (CVD) mortality and technical failure.
Totally 1632 patients (46.9?±?15.3?years old, 60.1% male, 25.6% with diabetes) were included. Among them, 149 (9.1%) had a 30-day unexpected rehospitalization after discharge. PD-related peritonitis (n?=?48, 32.2%), catheter malfunction (n?=?30, 20.
